HarshitKamriya/Vocal-Web_app ? reverse-engineered prompt

Build me a mobile friendly web app for visually impaired users that acts like a voice guided vision assistant.

It should have a simple home screen with a Start button and a Help page, then a live detection screen that uses the camera to identify objects and speak the results out loud. I also want a way to detect Indian currency notes, from ₹10 up to ₹2000, with voice feedback. Add an emergency mode that activates when the user holds a button for a couple seconds, sends an SOS style alert, and shares the current location if possible.

Make it feel easy to use on a phone, with big buttons, clear colors, and audio guidance throughout. It should work as a small full stack app with a frontend, a server, and the AI model files wired in. If you need current docs for browser camera, speech, or location features, look them up online and use the best approach.
